Antifungal drug perfusion through fungal biofilm on black polycarbonate membrane showing moderate zone of inhibition around the left most discs of the lower two plates i.e. panels c and d, whereas in rest of the six sectors (two each in panels a and b; one each in panels c and d), there is no zone of inhibition suggesting that antifungal agent did not perfuse through the biofilm developed on the polycarbonate membrane. All the eight organisms tested were Aspergillus flavus isolates from orbital pus, sinus drain and biopsy materials
